PROBLEM TO BE SOLVED: To adjust a turning angle in a jump-up direction of an operating lever box, in an operating device for a construction machine. SOLUTION: The operating lever box 3 is supported to a turning support bracket 4, fixed to the side of a driver's seat 1 of the construction machine so that the operating lever box 3 is turnable around a rotating shaft 29. A stopper bolt 34 is mounted to the lower end of a guide bar 25, serving as a guide, when turning the operating lever box 3 between a working position and a jump-up position. The tip position of the stopper bolt 34 is adjusted to make adjustment of the angle of the stopper bolt 34 until abutting on a guide pin 26, when turning the operating lever box 3 in the jump-up direction.
